The problem associated with an interface crack between anisotropic dissimilar media subjected to a remote heat flux as welt as traction on the crack surface is studied in this article. Based on the complex variable representations of the plane elastic problem developed by Lekhnitskii and a special technique of analytical continuation, the full field solutions of the displacements and thermal stresses are obtained in closed form. It is indicated that the nature of singularities in the stress field at the crack tips is unaltered by the presence of an applied heat flux if the heat conductivity coefficients obey the Onsager reciprocal relations. The explicit expressions for the strain energy release rate and crack opening displacements are also provided. The former is treated as the fracture parameter to characterize the occurrence of interface cracking. Numerical examples for graphite / epoxy composite bonded to metal and ceramic materials bonded to metal substrates are examined and detailed results are given. |
